Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20678, here are decompositions:

37 + 20641 = 20678
67 + 20611 = 20678
79 + 20599 = 20678
127 + 20551 = 20678
157 + 20521 = 20678
199 + 20479 = 20678
271 + 20407 = 20678
331 + 20347 = 20678

Showing the first eight; more decompositions exist.
